Reproducing Theater Ambience Introducing the Surround Modes

In a movie theater, many speakers are located on the walls to reproduce impressive multi-surround sounds, reaching you from all directions.

With these many speakers, sound localization and sound movement can be expressed.

Surround modes built in this receiver can create almost the same surround sounds as you can feel in a real movie theater.

■Dolby Surround

Dolby Digital EX*

Dolby Digital EX is newly introduced surround encoding format as an extension of multi-channel Dolby Digital, designed to add an extra surround channel to Dolby Digital 5.1-channel (see below). By using a matrix encoding/decoding method, additional “surround back” channel signal is encoded (and decoded) in both the left and right surround channel signals.

Compared to the conventional Dolby Digital 5.1-channel, this newly added surround back channel can reproduce more detailed movements behind you while viewing the video software. In addition, surround sound localization will become more stable, so that you can enjoy a realistic surround field in your listening room.

Best used to reproduce multi-channel movie sound tracks of the

software encoded with Dolby Digital EX ( ).

•To enjoy the software encoded with Dolby Digital EX, connect the source component using the digital terminals on the rear of this receiver. (See page 13.)

Dolby Digital 5.1-channelencoding method (so-called discrete 5.1-channel digital audio format) records and digitally compresses the left front channel, right front channel, center channel, left surround channel, right surround channel, and LFE channel signals (total 6 channels, but LFE channel is counted as 0.1 channel, therefore, called 5.1-channel).

Since each channel is completely independent from the other channel signals to avoid interference, you can obtain a much better sound quality with better stereo and surround effects.

•To enjoy the software encoded with Dolby Digital, connect the source component using the digital terminals on the rear of this

receiver. (See page 13.)

*Dolby Digital software can be roughly grouped into two categories

—multi-channel (up to 5.1-channel) and 2-channel software. To enjoy surround sounds while playing Dolby Digital 2-channel software, you can use Dolby Pro Logic II.

Dolby Pro Logic II*

Dolby Pro Logic II has a newly developed multi-channel playback format to convert all 2-channel software into 5-channel (plus Subwoofer). Matrix-based conversion method for Dolby Pro Logic II makes no limitation for the cutoff frequency of the surround treble and enables stereo surround sound unavailable with conventional Dolby Pro Logic.

Dolby Pro Logic II can reproduce spacious sound from original sound without adding any new sounds and tonal colorations.

Dolby Pro Logic II has two modes—Movie mode and Music mode:

Pro Logic II Movie (PL II MOVIE)—suitable for the reproduction

of Dolby Surround encoded sources bearing the mark . You can enjoy a sound field very close to the one created with discrete 5.1-channel sounds.

Pro Logic II Music (PL II MUSIC)—suitable for the reproduction of any 2-channel stereo sources. You can enjoy wide and deep sound by using this mode. For this mode, you can make precise adjustments to match the sound to your taste.

•When Dolby Pro Logic II is activated, the PRO LOGIC II indicator lights up on the display.
